Video tracking of marine invertebrate larvae
The tropical barnacle, Balanus amphitrite, is an economically important fouling species (it settles on natural and artificial submerged surfaces) with a short generation time and larvae that are relatively easy to culture in the laboratory. These attributes have contributed to its acceptance as a model species for larval settlement studies. The settlement stage larva the cyprid (figure 1) measu...
متن کاملSize-specific predation on marine invertebrate larvae.
Predation on planktonic larval stages is frequently a major source of mortality for the offspring of benthic marine invertebrates. Mortality rate likely varies with larval size and developmental stage, but few experiments have measured how these factors affect predation rates. I used experimental reductions in egg size to test how variation in larval size affects the likelihood of predation dur...
متن کاملEcological regulation of development: induction of marine invertebrate metamorphosis.
In the marine environment a wide range of invertebrates have a pelagobenthic lifecycle that includes planktonic larval and benthic adult phases. Transition between these morphologically and ecologically distinct phases typically occurs when the developmentally competent larva comes into contact with a species-specific environmental cue. This cue acts as a morphogenetic signal that induces the c...
متن کاملMarine Invertebrate Larvae Associated with Symbiodinium: A Mutualism from the Start?
Symbiodinium are dinoflagellate photosynthetic algae that associate with a diverse array of marine invertebrates, and these relationships are comprehensively documented for adult animal hosts. Conversely, comparatively little is known about the associations during larval development of animal hosts, although four different metazoan phyla (Porifera, Cnidaria, Acoelomorpha, and Mollusca) produce ...
متن کاملA method for accurate measurements of the respiration rates of marine invertebrate embryos and larvae
Measurements of respiration rates are essential to quantify the energy requirements of embryos and larvae. Here we describe a 'pBOD' method that employs small (< l ml) Biological Oxygen Demand (BOD) glass vials in which embryos and larvae are incubated. A decrease in oxygen concentration is measured by injecting seawater from each vial into the measurement chamber of a standard polarographic ox...
